What is the difference between the 8 ohm and 16 ohm versions? What ramifications does this have for amplifiers to pair it with and application?

Usually you want to match the amp output impedance to load/speaker impedance for maximum power transfer from the amp to the speaker. But if you don't I don't think you will observed much of a difference in performance. Here is a link that discusses the issue: http://peavey.com/forum/viewtopic.php?f=19&t=22191

Higher ohms are always compatible. As long as you stay above 2 per channel or 4 bridged you'll be fine with this amp.

As far as I understand, there is no difference. The 80 indicates the 80 ohm impedance.

It usually means 8 ohms is the recommended speaker impedance. Using lower impedance speakers like 4 ohm draws more power from the amp and can cause the amp to overheat. But generally in quality amps this will only be a real concern if u constantly blast music close to maximum levels. Some higher end brands will say they are 8 ohm but 4 ohm stable meaning they can handle the lower impedance

Hello Popi, I am not sure I understand your question, but I will give you an overall way to work out your speaker needs. An amplifier is rated by its ability to put out a maximum number of watts into an 8 ohm speaker without distortion (typically 2% at most). An amp will drive a speaker at 4 or 16 ohms as well with varying power numbers and volume. It is important that the amp sees an impedance level of 4-16 ohms or it won't operate well (meaning efficiently and possible overheating or shutting down). It is better to have the amp power rating equal to or higher than the speaker rating. An amp overdriven can clip and suffer damage. If you respond with what your amplifier is, mono or stereo, and what it's exact power output rating is I can be more accurate. Are you planning to drive 4 speakers at 8 ohms each?

This amp has four channels if you are only using two channels it will be 4 ohms per channel.If you are using all four channels it will be 8 ohms per channel.Ensure that the speakers are wired accordingly(most likely series parallel as you have 8 speakers most likely of 8 ohms).The ohms at the amplifier terminals can be higher than 4 ohms per channel but never lower (in 2 channel mode).

Impedance it selected at the Amp or Receiver, I don't see why not. I have all 8 Ohm speakers, so this is not an issue for me. You can't mix/match 8/6/4 Ohm. Hope this helps!

My understanding is 2 OHM is better. I would however recommend you install the amp to get the proper sound that the speakers are capable of. I have not done this but I need to.

It's ok but you will need to be careful with the gain setting if u wire it to 1 ohm. And if 1 ohm doesn't sound good try it at 4 ohms. What kind of amp? Is it a monoblock? Amp makes a difference

I would keep at 2ohm. I have 2 12's running at 2ohm. This amp lies about the power it has.

On a 4 OHM output amp. You use one 4 Ohm speaker or two 8 OHM speakers. Example: One 8 OHM speaker + One 8 OHM speaker = 4 OHMs.

Unlike Solid State Amplifiers where output power is dependent on Power Supply robustness, Device Ratings (eg Power Transistor) and load impedance in OHMs (ie your speaker impedance), a Vacuum Tube Amp is typically Transformer Coupled (Output Tube &gt; Transformer &gt; Speaker). Many Transistor Amps scrimp on Power Supply or Output Transistor so that power into various loads cannot be easily determined. Were those parts "up to snuff" then power into 4 ohms is double the power into 8 ohms. If there is a spec where the power is not doubled with a 4ohm load vs a 8ohm load, this is a clue that compromises were made and dynamic (real music) playback may be stressed. With a transformer-coupled amplifier (Vacuum Tube or Solid State, although SS is rare after about 1970) the power is always the same into any load the transformer has a winding for. So, typically, 4, 8 and 16 ohm loads would be the same power (eg 10w/4ohm, 10w/8ohm, 10w/16ohm). Although a 16 ohm tap on the transformer is rare today, most can be re-configured to provide a 16 ohm tap. Since there is no power penalty by going to 16ohms, and since damping factor doubles when impedance doubles, a 16 ohm speaker on a tube amp would provide very robust and tight bass response (for example).

They're 8 ohm impedance speakers. Will work with any receiver or amplifier expecting to see an 8 ohm load.Many 12v amps are looking for a 4 ohm load, which I think is what you're referring to. Some are switchable. You can wire these in parallel to get 4 ohms, but I doubt that would be practical for you, since you'd need to install two pair in order to do it properly. If your amp/receiver is expecting a 4 ohm load don't get these.

I did some brief reading about how to match amps and speakers, and my understanding is that the amp's power rating should be less than that of the speakers--around half the peak rated wattage. But as well as power you have to make sure the impedance of the speakers matches the output impedance range of the amp. If you're running two 8 ohm speakers in parallel on each channel, that's actually 4 ohms, so check those numbers. We use this Grace BTAR122 in conjunction with two 80 watt Polk Atrium 4 speakers and it sounds fantastic.

Thanks H. Choi. I notice from the manual that it says use 8 - 16 ohms below the speaker terminals, but one doesn't have to believe everything they tell you. :-)

That's a quite complex question you should look it up online to know more. Simply said you can play a sub at 1,2 or 4 ohm. It's takes a weaker amp to power at 1 but it also puts more stress on the speakers. At 4 ohm it would be hard to fully supple the power. Your best bet is to look up wiring for 2 ohm or 4 ohm subs and match it with what is in your car or when your planning to have. You can't simply say one is better than other. Amplifiers have diffrent ohm they supply to depending on the amp type and setup.

Most current amplifiers can handle 6 ohm speakers without problem (though power output will go up, so pay attention to that). It's 4 ohm speakers where you'll start having serious problems - you'll need an amp that explicitly states it supports high current output. Check your amp's user guide - it should have what impedance is supported.
